Which two processes commonly generate magma?
decompression melting and wet melting (the addition of volatiles) :)
Volcanos are usually formed as a result of?
Most volcanoes form at plate boundaries where melting of rock occurs in the upper mantle either as a result of thinning crust reducing pressure or from the introduction of volatiles.
Can you liquefy a rock?
Yes. Rock can be liquified by raising its temperature to that of the melting point of the mineral constituent with the highest melting point.
Is water a contributer to a rock's melting temperature?
Yes. The presence of water can significantly reduce the melting temperature of rock. For example the presence of water and other volatiles in a subducting slab of oceanic crust that acts to significantly reduce the melting temperature of the mantle material above it leading to the formation of magma and the volcanism that is associated with subduction zones.
Is metamorphic rock made of sedimentary rock and igneous rock?
No, metamorphic rock is rock that has been modified by heat and pressure (without melting). Usually it is sedimentary rock that is modified into metamorphic rock. The main modification is usually removal of moisture and other volatiles. Rarely an igneous rock might be modified, but as they are usually very low in moisture and other volatiles the modifications are typically only minor.

When magma forms within the mantle it is most often a result of?
Either the loss of confining pressure causing the melting point of the material to drop below the in-situ temperature or due to the presence of volatiles which enter the mantle where subduction occurs and also lower the melting point of the material.
How do melt rock?
There are three ways to melt rock to form lavas. You can use decompression, add volatiles, or conduction. All you need to do is use these strategies to get the rock to its melting point.
What are oleoresins?
They are extracts without volatiles
What year did the browning light twelve start having the gold trigger?
From the time of it,s introduction;which was the year 1947.
One of two conditions needed to melt minerals into magma?
crystallization above ground and crystallization below ground

Whayt is the definition of Non halogenated volatiles?
The definition of non-halogenated volatiles is a compound where a halogen is not attached. They are mainly analysed based on their solubility in water.Ê
What can global warming trigger?
Hurricanes, extreme weather (climate change), sea levels rising, glaciers melting, sea ice melting, animals dying out, pine beetles killing forests and much more.
